WILLIAM H. SUMMERS, OF FLORENCE, KANSAS.

APPARATUS FOR TREATING CRUDE OIL.

To all whom it may concern Be it known that I, WILLIAM H. SUMMERS, acitizen of the .United States, residing at Florence, in the county ofMarion and State of Kansas, have invented a certain new and usefulImprovement in Apparatus for Treating Crude Oil, of which the followingis a specification.

My invention relates to improvements in apparatus for treating crudeoil.

The object of m invention is to separate from the oil the thicker andheavier ingredicuts in the oil, such as paraffin, thick heavy oil,magnesia, sand, dirt and other impurities.

A further object of my invention is to provide an apparatus: which isSimple in construction, 0 ea to make, and to apply to a tank in the fied, which is durable and not liable to get out of order, which has largecapacity, which may be readily cleaned, and the screened material easilyremoved from the tank,-'and which is efiicient in operation.

The novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawing, which illustrates the preferred embodimentof my invention,

Fig. 1 is a vertical sectional view of a settlin tank provided with myimprovement.

1g. 2 is a top view of the same.

Similar reference characters designate similar parts in the differentviews.

1 designates an ordinary field settling tank of relatively largecapacity having an open top and an outlet or discharge pipe 2, adj acentto the upper end. v The bottom of the tank is preferably inverted coneshape having a central discharge opening 3 adapted to be closed by ashut-off valve 4. 5 deslgnates a supply pipe connected with any suitablesource of supply and having its lower end discharging into the tankadjacent to the bottom thereof, said pipe .servlng as the oil inlet forthe tank.

Extending transversely across the tank intermediate of the inlet 5 andthe outlet 2, is

a screen which is adapted to permit the passage therethrough of thelighter thinner part of the oil, but which intercepts and prevents thepassage therethrough of the heavier ingredients, such as thick heavy oiland parafiin and foreign substances, such as magnesia, sand or dirt.

The screening material is preferably canvas, which may be of a mesh bestsuited to Specification of Letters Patent.

arrest the particular ingredients or substances WhlCh may be carried byoil from different wells.

The screen is composed, preferably, of a plural ty of sectlons, eachsection consisting of a frame 6, having canvas 7, extending across theopemng in the frame and attached to the frame, each frame beingremovably supported u on suitable supporting devices, such as ang eirons 8, fastened to the inner wall of the tank 1. The frames 6 arearranged in aig-zag relationship to each other, with relatlonship to thehorizontal plane, whereby a large area of screening surface is In theoperation of my invention, the crude oil from a suitable source ofsupply, not shown, is discharged into the tank 1 through the plppo. Thevalve 4 is normally closed. The t 'nner lighter oil passes through thecanvas 7 and is discharged from the tank through the outlet pipe 2. Theparafiin, thick heavy oil, sand and dirt and other thick heavysubstances are arrested by the canvas screening 7 and fall by gravity tothe bottom of the tank, from which they can be removed from time to timeby opening the valve 4;.

When desired, the frames 6 can be independently removed for the purposeof being cleaned or for the renewal of worn-out screening material,after which the frames may be replaced in thein operative positions.

I do not limit my invention to the structure shown and described, asmany modifications, 1 within the S00 e of the appended claims, may bemade without departing from the s 1rit of my invention.

at I claim is V a 1. In an apparatus for treating crude oil, a settlingtank having an inlet for oil and an outlet for oil above saidinlet,supports attached to the inner wall of the tank and arranged in zig-zagrelation to each other, and a screen extending transversely entirelyacross the tank intermediate of the inlet and the outlet and comprisingsections, each be-' Ill of said tank, and removable screen sections,each comprising frames across which screening material is attached, eachof said screen sections being independently removably mounted on saidzig-zag supporting means and being in zig-zag relation to each other iand extending as a Whole entirely acro the I tank, substantially assetforth.
